Design of IoT Platform Based on Distribution Automation System
The existing distribution automation s ystem can only monitor electrical signals and cannot monitor various environmental signals.The sensors,communication,and main stations of various manufacturers monitoring environmental signals in the market are all integrated,and data from each manufacturer is not shared,which is not conducive to large-scale popularization.To achieve the integration of various sensors into the distribution automation system through a dedicated network,enabling the interconnection and interoperability of sensor data and electrical signal data,a set of IoT platforms based on the distribution automation system is designed.The IoT platform based on the distribution automation system establishes a dedicated virtual private network(VPN),where sensors and video monitoring devices are connected to the IoT platform through a wireless VPN through a firewall.The distribution terminals are directly connected to the distribution automation system using VPDN,thereby achieving the interconnection of sensor data and electrical data.Modularize the power supply,communication,and protocol functions of sensors to achieve sensor universality,facilitating their widespread application in the electricity market.
